Lithuanian Citizenship by Descent

Lithuania treats diaspora claims as restoring citizenship that existed before the Soviet occupation. Under the 2016 Law on Citizenship, a person who held Lithuanian citizenship before 15 June 1940, and their children, grandchildren and great-grandchildren, can have it restored. The law stops at great-grandchildren. There is no language test and no residence requirement.

The proof that matters is the ancestor's citizenship before 15 June 1940: an interwar Lithuanian passport, an internal passport record, military or census entries, or registry records. Being born in the Russian Empire before 1918, in what is now Lithuania, is not by itself proof of Lithuanian citizenship.

One trap catches many American families: under the interwar law, becoming a citizen of another country ended Lithuanian citizenship. An ancestor who emigrated in the 1920s and naturalized in the US before 15 June 1940 was no longer Lithuanian on that date, so restoration through them fails — Lithuania's courts have rejected exactly these cases. Check the naturalization date before you spend money on archive research.

Lithuania normally does not allow dual citizenship, but restoration has a major exception. If your ancestor left Lithuania between 1918 and 11 March 1990, the day independence was restored, and did not relocate willingly to the USSR, you can hold Lithuanian citizenship alongside your current one. That covers most families who emigrated to the United States, Canada, the UK, Australia or South America.

If the exception does not apply, restoration requires giving up your other citizenship. A May 2024 referendum on allowing dual citizenship more widely failed to reach the required turnout, so this rule still stands.

You need birth and marriage records linking each generation to the ancestor, proof of the ancestor's pre-1940 citizenship, and evidence of when and where they left. Foreign documents need apostilles and certified Lithuanian translations. The Lithuanian Central State Archives and the Migration Department can help locate interwar records.

Applications go to the Migration Department, through a Lithuanian embassy or consulate if you live abroad. Once citizenship is restored, you can apply for a Lithuanian passport.

Restoration applications go to the Migration Department, directly or through a Lithuanian embassy. You'll need proof that your ancestor was a Lithuanian citizen before 15 June 1940 — an interwar Lithuanian passport, an internal passport record, a military record, or a certificate from the Lithuanian Central State Archives — plus birth and marriage records linking each generation, apostilled and translated into Lithuanian.

Two archive searches settle most cases: the Lithuanian Central State Archives (for interwar passports and citizenship records) and the Lithuanian State Historical Archives (for church books). If your ancestor naturalised elsewhere before 15 June 1940, they lost Lithuanian citizenship then — and the line fails.
